'function' is what activity/operation the LED is associated with. It is
a fixed set of strings which s/w may use. It is a replacement for
'linux,default-trigger'.

'label' is what is printed next to the LED for a human to read. 'label'
can be anything and the OS shouldn't care what it is.

They serve 2 different purposes.
